It depicts the god Ea with the upper body of a goat and the lower body of a fish. Ea was the father of the chief god Marduk in Babylonia, and the god of water and wisdom. It was passed down to Greece in the form of a goat-fish and was called Aegokeros. It gradually became the same as the goat-shaped faun Pan. Pan is said to be the son of Hermes or Zeus, with the upper body of a human and the lower body of a goat, and has goat horns. Long ago, when the gods were gathered in Egypt, they were attacked by the monster Typhon. The gods were frightened and transformed into various forms. In the story, Pan jumped into the river and escaped by turning into a goat above the water surface and a fish below the water surface. It is said that Zeus added Pan to constellation because his appearance was so comical. [Source of the story] Encyclopedia of the Cultural History of Stars, Hakusuisha Publishing Co., Ltd.

When the Ethiopian royal family was ruled by King Cepheus and Queen Cassiopeia, Cassiopeia, who was very beautiful and self-respecting, said, "My beauty is no match for the daughters of the god of the sea." When Poseidon, the god of the sea, heard this, he became angry and sent a large whale living in the sea to Ethiopia to cause a tsunami. To settle this disaster, Cassiopeia and Cepheus sacrifice their daughter Andromeda in accordance with the trust.
